Every few days when we open the POS in the morning we get a file corrupt message and the POS will not open. It appears the main mdb file is corrupt. If I copy the three backup files from the previous days backup and put them in the POS main directory then everything works again. Is the main mdb file not getting closed properly when closing the program for the day? I have been using this program for a few years now without any problems and in the last few weeks this has been occurring. Any help would be appreciated. Thanks
